BIOSENSE™ Helps You Succeed By Providing All Day Feedback While Monitoring Your Ketone Levels Throughout Your Nutritional Ketosis Therapy

ACEs Reading

Published studies and our own clinical research has shown that blood and breath ketones are closely related. This correlation increases significantly with multiple measurements per day as recommended with Biosense.

Color Indication

The BIOSENSE™ device and mobile app put your measurement into context by providing a color indicator along with your ACEs reading. The vertical black bar on the results screen indicates where your measurement falls on the overall spectrum of ketosis.

Easy Synchronization

BIOSENSE™ stores up to 100 measurements directly on the BIOSENSE™ device and automatically transfers the data to Cronometer, as well as the BIOSENSE™ app on your phone.

BIOSENSE™ Clinical Trial

BIOSENSE™ manufacturer Readout Health completed a 19-subject clinical trial in the fall of 2019. We selected healthy individuals and we asked them to simultaneously measure their blood and breath ketones 5 times per day for 14 days to get consistent results.

Behind The Technology

The required deep lung sampling process provides accurate and reproducible measurements by correcting for natural variations in exhalation time and lung capacity across individuals. BIOSENSE™ is the only breath monitor to provide this patented technology.
